目的:根据北京市某肠道门诊就诊患者的腹泻监测数据,建立预警控制图,为腹泻病防控提供早期预警。方法:收集北京市某三级综合医院肠道门诊2009年(2009-04-01至2009-10-31)和2010年(2010-05-01至2010-11-10)开诊期间就诊患者的病历监测资料,根据移动平均法,计算发病基线,确定概率界值α和μα,利用公式w=珔Xj+μαSj计算预警值,绘制预警控制图。结果:根据疾病的危害性、严重性和可控制等特点,确定概率α为0.01,则μα(单侧)为2,计算各预警值,依次得出了该肠道门诊腹泻病、细菌性痢疾和其他感染性腹泻的预警控制图。结论:该肠道门诊的腹泻预警控制图需要进一步收集基线数据加以评价和不断调整,以得出符合该肠道门诊的最佳预警模型。
OBJECTIVE: To establish an early-warning control chart based on the data of diarrhea monitoring in an intestine outpatient clinic in Beijing to provide early warning for the prevention and control of diarrhea. Methods: The clinical data of patients admitted to the gut clinic of a tertiary general hospital in Beijing from 2009-04-01 to 2009-10-31 and 2010 (2010-05-01 to 2010-11-10) were collected. Medical records monitoring data, according to the moving average method, calculate the incidence baseline, determine the probability boundary values α and μα, use the formula w = 珔 Xj + μαSj calculate the early warning value, draw the early warning control chart. Results: Based on the characteristics of the disease, such as the severity, severity and controllability, the probability α was determined to be 0.01 and the μα (one-sided) to 2. The precautionary values were calculated and the GI clinic diarrhea, bacillary dysentery And other infectious diarrhea early warning control chart. CONCLUSIONS: The diarrhea early warning control map for this gut clinic needs to be further collected for baseline evaluation and continual adjustment to arrive at the best early warning model for the gut clinic.
